All five incineration lines at the centralized sludge treatment and disposal project in the Lisha Island Fine Chemical Park, Shatian Town, Dongguan City, have recently reached stable operational conditions. With a total investment of RMB 1.918 billion, the project is designed to process 2,000 tons of sludge per day (at 60% moisture content), making it the world's largest sludge mono-incineration project built in a single phase. With all five lines now running, 100% of Dongguan's daily municipal sludge is being harmlessly treated and disposed of.
The project adopts an "incineration + waste heat recovery + ultra-low emission" process, introducing Thermylis High-Temperature Fluidized Bed incineration technology from SUEZ Group. It is the first project in China's sludge sector to achieve zero liquid discharge (ZLD) of high-concentration wastewater.
This fully operational project now allows Dongguan to handle all of its dried sludge on-site and achieve full municipal sludge self-sufficiency.
